This is true if you're using Newtonian Physics, but thanks to Special Relativity (ugh, that again
) not only is it impossible to reach the speed of light, but the speed of light is always constant; so even if you were somehow travelling at 'c' (3e8 m/s ie. the speed of light) then light would still appear to be travelling faster than you, you wouldn't be able to 'overtake' any light waves (and hence 'go back in time').

Like I said before, the effects depicted in Star Wars and Star Trek (in terms of travel, not the flashing lights) do not require travelling faster than the speed of light, by travelling at 0.999999999 times the speed of light you can reach any point in the universe within a couple of seconds at most (and that is real physics, and is actually possible). Although by the time you get there Earth would have aged many billions of years (although the people in the spaceship would have only aged the few seconds which it took) - Special Relativity
.
EDIT: The whole faster than light business is based on Newtonian Physics which says that if you're travelling at 'v', you'll reach your destination in distance divided by 'v' seconds which is simply just WRONG in practice.
